I have been/am interested in the following areas:

- Supersymmetric indices and connections to algebraic/geometric structures.
- Exact results in 3d N=4 theories and 3d mirror symmetry.
- Integrability and enumerative geometry and geometric representation theory in supersymmetric QFT.
- Singular perturbation theory, Borel resummation and resurgence.
